NEWS RELEASE

For Immediate Release

          PROXY MONITOR RECOMMENDS THAT WILLAMETTE SHAREHOLDERS VOTE
                           FOR WEYERHAEUSER NOMINEES


FEDERAL WAY, Wash., May 24, 2001 - Weyerhaeuser Company (NYSE: WY) today
announced that Proxy Monitor recommended that Willamette Industries, Inc.
(NYSE: WLL) shareholders vote FOR the Weyerhaeuser slate of director nominees
at Willamette's Annual Meeting scheduled to be held on June 7, 2001.

Proxy Monitor is widely recognized as a leading independent proxy advisory
firm. Many institutional investment firms, mutual funds, and other fiduciaries
throughout the country rely upon its recommendations.

In reaching its decision to recommend that Willamette shareholders vote FOR
the Weyerhaeuser nominees over the Willamette slate, Proxy Monitor stated in
its May 24, 2001 report that:

     "[O]ne has to wonder whether the Willamette board would accept ANY offer
     from Weyerhaeuser, or any other suitor for that matter. Management has
     consistently refused to negotiate with Weyerhaeuser, has not given any
     indication of a price it might accept, and has not looked for other
     buyers. Instead, the board's strategy seems to be concentrated upon its
     own survival."

     "[T]he Willamette board appears to have lost sight of the fiduciary
     responsibility it owes to its shareholders and, for that reason, its
     credibility as well."

     "Willamette's agreement with its financial advisor in this contest,
     Goldman Sachs & Co., is eye-popping as well."*


Weyerhaeuser noted that Willamette is paying Goldman Sachs $30 million to
prevent a transaction with Weyerhaeuser.

Steven R. Rogel, chairman, president, and chief executive officer of
Weyerhaeuser, said, "We are pleased that Proxy Monitor has joined
Institutional Shareholder Services in recommending that Willamette
shareholders vote for the Weyerhaeuser director nominees. We believe that the
current Willamette board will not sell the company at any price. At
Willamette's Annual Meeting, shareholders will have the opportunity to send a
message to the Willamette board that cannot be ignored by electing directors
who are committed to maximizing value for shareholders now."

Weyerhaeuser is seeking the support of Willamette shareholders for the
election of the three Weyerhaeuser nominees to Willamette's board at the
Willamette Annual Meeting. Weyerhaeuser urges Willamette shareholders to sign,
date and return the GOLD proxy card today voting FOR the election of the
Weyerhaeuser nominees. For more information about how to vote for the
Weyerhaeuser slate of director nominees, shareholders can call Weyerhaeuser's
proxy solicitor, Innisfree M&A Incorporated, at 1-877-750-5838 (toll-free).

changes in economic activity in Europe and Asia, particularly Japan, and by
